This invention relates to a device for cleaning the folding blades of a folding machine while the machine is in operation.

The principal objects of the invention are to provide means connected with thek folder for cleaning both sides of the folding blades during each operation of the machine, and thus keeping the blades free from ink and preventing the smutting of the papers by the w accumulation of ink on these blades; and (in l showing modified forms.

-carry freshly printed matter and the preferred form) to provide such device in an automatic form operated by the folder.

Other objects and advantages of the in vention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. l is an end view of a folding machine, partially diagrammatic in form, showing a preferred form of this invention; Y Fig. 2 is a sectional view of the cleaning means and folding blade;

Fig. 3 is a side view of the folding cylinder and cleaning means, and

Figs. 4 and 5 are views similar to Fig. 2,

Folding' cylinders on newspaper printing presses are equipped with two folding blades which fold the paper into a half age fold and tuck it into the folding rolls. s the papers this printed surface comes into contact with both sides of each foldin blade, it is found that an accumulation o ink appears on the blades after a short time. This has a tendency to smut subsequent papers. This invention is designed to remove this ink from the folding blades so as to avoid this difliculty.

Referring to Figs. 1, 2 and 3, I have shown the invention as applied to a folding couple A.comprising a folding cylinder 10 and a cutting cylinder 11. The folding cylinder is provided with folding blades 12 as usual, which deliver the folded product into contact between the folding rolls 13. Each folding blade is mounted on a shaft 14 which extends across the machine, and is operated through a stationary gear 15 and a set of gears 16. Thus the folding blades rotate on their own axes while the folding cylinder is in operation, and in the design shown each folding blade is projected outwardly in a radial direction :three times during each rotation of the folding cylinder. At one of these points it tucks the folded product into the ybite of ther folding rolls.

A In accordance with the present invention,

1 makeuse of the fact that each blade 12 A moves out radiallyat other points and clears the blades vwhen they so project, preferably at olie of the other points in the circumfergear 19 is a gear 20 which meshes with a gear 21 on the folding cylinder, thus kee ing these rolls in constant rotation through out the operation of the folding cylinder. It will be seen therefore that as the blade comes toa point between these rolls, its vopposite sides will be" wiped free of ink and then the blade will passout of contact with them as indicated in dotted lines in Fig.2. V The blades do not' 'always come into contact with the same spots on the wiping rolls, so these surfaces lasta long time without becoming satu` rated with ink. i

Itis not necessary that the cleaning device be movable or rotary, and in Fig. 4., I have shown a pair of stationary blocks 23 each covered 'with alayer 4.of rubber or felt 24. The Ysurfaces between which the blade `12 yengages are convex as in the case of the rollers4 ,suicient for the`-v purpose,
